Raw underway Thermosalinograph (TSG) observations from the Cape Canyon Exploration Cruise on Algoa Voyage 247, March 2018
Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected between 05 March and 28 March 2018 during the Cape Canyon Exploration Cruise on the RS Algoa Voyage 247. A SeaBird SBE45 TSG is used to opportunistically collect underway near-surface temperature and conductivity measurements during research and monitoring cruises. Water is continuously pumped to the TSG from an intake located in the hull of the vessel, and the observations are continuously interfaced with...

Averaged bottom temperature and dissolved oxygen in and around the Cape Canyon
Submarine canyons are internationally reported to enhance upwelling and heterogeneity. However, in South Africa such studies remain limited and thus a knowledge gap in regional submarine canyon dynamics still exists. To address this gap, the Department of Forestry, Fisheries and the Environment: Oceans and Coasts initiated a multi-disciplinary expedition onboard the RV Algoa (March 2016-2018) where oceanographic data, amongst other datasets, was collected within a 5x5 nautical mile distance....
Benthic invertebrate presence data, in and around the Cape Canyon (Southern Benguela Upwelling region)
Canyon research is still an emergent field in South Africa and the true potential of canyons as biodiversity hotspots has seldom been studied in an integrated context. In response to this, the Department of Forestry, Fisheries and the Environment: Oceans and Coasts collected benthic data to better understand benthic species profiles within and around the Cape Canyon. This equated to 39 stations (whereby 13 were canyon and 26 non-canyon) and yielded 180 species.
Cape Canyon Benthic Invertebrates Tissue samples
Submarine canyons are heterogeneous environments known to support a variety of benthic organisms, and often considered biodiversity hotspots. Canyon morphological features facilitate the funneling of organic matter to the seabed, making them significant hubs of food resources for benthic life. In light of this, the DFFE: Oceans and Coasts initiative undertook the collection of benthic tissue data aimed at understanding how hydrography affects food availability for benthic species within and...
Cape Canyon Suspended Particulate Matter CTD water sample
The Cape Canyon, situated on the western continental shelf of South Africa, stands as the country's largest bathymetric feature. Despite its prominence, understanding of the food web dynamics within the system and the significance of the benthic community for higher trophic levels remains incomplete. In response to this knowledge gap, the DFFE: Oceans and Coasts launched a multidisciplinary expedition aboard the RV Algoa. The expedition aimed to characterise the physical environment and...
